椰子介壳虫（CSI）的主要爆发发生在菲律宾，2010年至2016年发生在吕宋岛南部的塔霍河地区，2017年至2020年发生在棉兰老岛的三宝颜半岛。Calauanica的寄生对暴发管理的贡献需要量化。我们的评估发现C. calauanica，自然发生在南部塔霍河。在三宝颜半岛也有类似的发现，在那里大量饲养的C。从南部Taganja calauanica释放生物防治。在1至2年期间，2014年至2016年在南塔吉，2018年至2020年在三宝颜半岛，CSI的人口显着减少，同时发现受感染的椰子树恢复。与南塔霍河的综合害虫管理（IPM）计划相比，三宝颜半岛的综合害虫管理计划对化学防治的依赖程度较低，该地区没有记录到重大的气候干扰。我们的研究结果有力地表明，生物防治已成为一个非常重要的因素在管理A。僵硬C.应建立和维持calauanica作为生物控制剂，特别是在不同地区，以便能够对CSI入侵该国的新地区作出快速反应。2010年至2015年期间，椰子介壳虫Aspidiotus rigidus Reyne在菲律宾吕宋岛南部的塔吉特地区的椰子种植园和林地中引起了重大害虫爆发。为了确定是否由Comperiella calauanica Barrion，Almarinez和Amalin（一种本地encyrtid）寄生可能是到2015年最终控制疫情的一个因素，我们估计并评估了其在A.在三个采样期内，从南部塔格地区三个省的选定点实地收集的样品上的硬菌菌落。我们观察到C. calauanica始终只发生在A. 2014年至2015年，南塔加禄地区出现了硬蜱种群，寄生率很高。相关分析和回归分析结果表明，该虫的寄生性依赖于寄主密度。卡拉乌尼卡在现场。A.从2014年第三季度到2016年第二季度，椰子树的硬度与肉眼可见的恢复同步记录。A.刚性种群的同时，大量饲养和释放的C. calauanica于2018年至2020年在三宝颜半岛发现。我们的研究结果和观察表明，寄主特异性寄生的C。calauanica的生物防治作用可能有助于最终控制A.在南部塔格鲁地区以及三宝颜半岛，在接种C. calauanica。
Major outbreaks of the coconut scale insect (CSI), Aspidiotus rigidus, occurred in the Philippines, between 2010 and 2016 in the Southern Tagalog region of Luzon Island, and from 2017 to 2020 in the Zamboanga Peninsula, Mindanao Island. Contribution of parasitization by Comperiella calauanica to the management of the outbreaks needed quantification. Our assessments found very high percent parasitization by C. calauanica, which occurred naturally in Southern Tagalog. Findings were similar in the Zamboanga Peninsula, where mass-reared C. calauanica from Southern Tagalog were released for biological control. Significant decreases in the population of CSI were recorded in 1- to 2-year periods, 2014 to 2016 in Southern Tagalog, and 2018 to 2020 in the Zamboanga Peninsula, with parallel findings of recovery by infested coconut palms. Compared to the integrated pest management (IPM) program in Southern Tagalog, that in the Zamboanga Peninsula relied less on chemical control, and no major climatic disturbance was recorded in the region. Our findings strongly suggest that biological control has been a very important factor in the management of A. rigidus. Rearing facilities for C. calauanica as biological control agent should be established and maintained, especially in the different regions, to enable quick response to new areas of CSI invasion in the country. The coconut scale insect, Aspidiotus rigidus Reyne, caused a major pest outbreak in coconut plantations and stands in the Southern Tagalog region of Luzon Island in the Philippines between 2010 and 2015. To determine if parasitism by Comperiella calauanica Barrion, Almarinez and Amalin, a native encyrtid, could have been a factor in the eventual management of the outbreak by 2015, we estimated and assessed its parasitization levels on A. rigidus colonies on field-collected samples from selected points in three provinces in the Southern Tagalog Region across three sampling periods. We observed that C. calauanica consistently occurred only in areas where A. rigidus populations occurred, with high parasitization levels in the Southern Tagalog sites from 2014 to 2015. Results of correlation and regression of total scale count against parasitized scale count suggest putative host density-dependent parasitism by C. calauanica in the field. A marked decrease in the abundance of A. rigidus was recorded concurrently with visually observable recovery of coconut trees from the third quarter of 2014 up to the second quarter of 2016. Similar results of significant reduction in A. rigidus populations concurrent with high percent parasitization by mass-reared and released C. calauanica were found in the Zamboanga Peninsula from 2018 to 2020. Our findings and observations altogether suggest that host-specific parasitization by C. calauanica effected biological control, which may have contributed to the eventual management of the A. rigidus outbreak in the Southern Tagalog Region, and also in the Zamboanga Peninsula where similar recovery of coconut trees were observed within a year after inoculative releases of C. calauanica.
